SLITTING- AND SCORING MACHINE.

Specification. of Letters Patent. P'ai gnted Dial, 24, 1914.

Application filed November 7, 1912. Serial No. 729,942.

To all whom it may concern:

Be it known that I, JEFFREY T. FEB-RES, a citizen of the United States, residing at Los Angeles, in the county of Los Angcles and State of California, have invented certain new and useful- Improvements in Slit.- ting and Scoring Machines, of which the following is a specification.

My invention relates to machines for either slitting or scoring or bothslitting' and scoring paper board or corrugated paper board or the. like, and the object of my invention is to produce a machine of this character having a plurality of sets of slitters or scorers or both, any. one set of which is adapted to be brought into operative position leaving another set inoperativathe dif-- ferent sets having different adjustments for the slitting and scoring; Moreover, my construction is such that the bringingof any one set to operative position automatically brings its driving mechanism intoo'perative positionI V a In the drawings Figure l is a side elevation of my machine; Fig. 2 an end elevation thereof; Fig. 3' a section on the line 3 Fig. 1; Fig. 4 a cross-section on the line 4-4.-

of Fig. 1. but on-alarger scale; andFig.

a section on the line of Fig. 4.

Referring to the present embodiment of my invention as illustrated in the drawings my machine is provided with a frame of suitable size and dimensions consisting of the end framesl adapted to rest upon the floor or support and a horizontal cross-beam 2'connected at its ends to said end frames ,at points intermediate their height. .At the 'upper ends of the end frames is mounted a nevolving frame comprising thcopposite end members or bars 3 and two opposite crossbars 4 connecting the ends of said end bars respectively. This revolving frame is pivoted at one end upon the bolt or stud and at the other end upon theslceve 0 which is mounted in the end members 3 and secured in proper position therein by the set screw 7 This sleeve has an eccentric bore receiving the shaft 8 which is driven in any suitable manner, as by the pulley 9.

At points on either side of the axis of rotation of the revolving frame are arranged two sets of parallel shafts 10. 10 and 11. llwhose ends are journaled in the end bars 3. By preference these shafts are provided with pinions 12, and 13. although if'de'sired the pinions on the outermost shafts might be dispensed with. in which event the friction of the scorers and slitters would be depended upon for rotation of such shafts. In the position of the revolving frame as illustrated in the patent drawings the pinion 12'meshes with a driving pinion 14 on the inner end of the drive shaft 8 but at this time the other pinion 13 is out of mesh with the pinion 14. Each. of the shafts 10, 10 and 11, 11 carries horizontal driving one or more slitters 1:) and'one or more scorers 16 of any suitable or desirable construction but arranged to be adjusted longitudinally on their shafts in order to provide for slitting and scoring along different lines onthe paper as required in practice in the forming of different constructions of boxes. It will be understoodthat the paper board is passed through this machine in a horizontal planebetwo'en the two members of a set of slitters and scorers. The'lowermost slitters and scorers which are here represented as being secured to the shafts 10 are, the ones which are in operative position.

Assuming that the work by the particular slitters and scorers here shown in operative position has been completed and that it is desired to work upon paper board according to a different adjustment of slitters and scorers such as shown by the uppermost set in Fig. 1 in orderto producev a different "construction of'box, the movable frame is rotated 180 with the result that the position of shafts l0 and 11 and their associated devices is reversed, automatically carrying the pinion 12 out of mesh with the driving pinion'll and bringing the other pinion 13 into mesh therewith. Thisautomaticmeshing and unmeshing of the pinions is accomplished by reason of the fact that the re-' vol ving frames revolve upn an axis (the bushing 6 and the stud 5) which is eccentric to the axis of the driving pinion 14, The revolving frame is held in its proper adjusted position in suitable manner "as by means of the lever 17 which is mounted at its inner end to the upstanding bracket 2 on the cross-bar 2. This lever is upwardly spring-pressed by the spring 18 which nor mally holds the lever in looking position between the lugs 19 extending upwardly from the cross-bars 4.

It will be understood that my machine may have two set positions of the slitters and scorers, thereby providing for two different constructions of box, but I prefer to have the slitters and scorers adjustable longitudinally on their shafts or arbors in order to providefor a great variety of constructions of box, thereby materially increasing the range of work of the machine. It is obvious that while the machine is in operation the uppermost set of slitters and scorers may be adjusted to any desired position' in order to be ready for work upon a different order or construction of box immediately upon the completion of the order or work their passing through the machine. In this mama-the time'is considerably reduced i-nasmuchas there'is no interim betweenthe' completion of one order and the start upon the next order.

It is intendedthat my machine shall operate upon paper or board as delivered from the board making machine and hence it is necessary that the machine of this application shall be placed in proper alinement therewith. In order to facilitate the work of setting the machine over in line with the other I employ the lever device shown in Fig, 1, which comprises a vertical hand lever 20 pivoted intermediate its lengthto the brackets 21 on one of the. sideframes 1 and carrying at its lower end a rod 22.

This rod terminates in or is provided with a p in 23 adapted to catch into a hole in the door indicated at 24. The pin 23 being a fixed point, it will be seen that a movement of the lever in one direction or the other will move the machine accordingly.

I claim:

. 1. In a machine of the class described, the combination of a rotatable frame, a plurality of devices mounted thereon for operating on the paper board one at a time, separate driving mechanisms for such devices, and a common driving means in operative relationship with one of'said mechanisms at a )time, said. frame being eccentrically nounted with respect to said means wherey one of said mechanisms will be disengaged from said means and another mechanism brought into engagement therewith.

2. In a machine of the class described, the combination of a frame, a'plurality of pairs of shafts arranged therein, slitting or scorframe being rotatable to bring one pair of shafts and their devices into operative position at a time, driving mechanisms for the shafts, and means common to said mechanisms for operating them one at a time, said mechanisms being mounted on but eccentri- V cally of said means to cause one mechanism at a time to be brought to operating position with respect to said means.

4. In a machine of the class described, the combination of a stationary frame, a rotatable frame supported thereby on a horizontal axis, a pair of shafts on each side of such axis, slitting or scoring devices on such shafts, a horizontal driving shaft, and driven connections for a member of each pair of shafts, said rotatable frame being mounted eccentrically on-said driving shaft whereby one driven connection is brou ht into operative relationship with the driving shaft and the other out of-operative relationship.

5. In a machine of the class described, the combination of a stationary frame, a rotatable frame supported thereby on a horizontal axis, a pair of'shafts on each side of axis, a pair of shafts on each side of such axis, slitting or scoring devices on such shafts, a horizontal driving shaft, an eccentric bearing sleeve received in the rotatable frame and receivin the driving shaft, a driving pinion on sucli shaft and a driven pinion on a member of each pair of shafts.

7. In a machine of the class described, the combination of a frame, a plurality of pair of shafts arranged therein, slitting or scoring devices mounted on said shafts, said frame being rotatable to bring one pair of shafts and their devices into operatlve position at a time, means for rotating the shafts when in such position, and a lever normally pressed into locking engagement frame and a, rod operated thereby to engage with the frame to hold it ative posit-ions.

8. In a machine of the class described, the i fi combination with the main frame, slitting --Wi-tnesses:

and scoring mechanism mounted therein in fixed relationship, a lever pivoted on the difl'erent operthe" floor or support fcrthe frame.
